Consider the following scenario:

• You have a multiprocessor computer that is running Windows XP, Windows Server 2003, or Windows Vista.
• You resume the computer from hibernation (S4).

In this scenario, the computer stops responding on a black screen.

Consider the following scenario:

• You have a computer that is running Windows Server 2008 or Windows Vista Service Pack 1.
• The computer has a Peripheral Component Interconnect (PCI) Express interface.
• You have at least one PCI Express card that does not fully support Active State Power Management (ASPM) inserted.
• You restart the computer.

In this scenario, an internal error may occur during restart. For example, a CPU IERR error may occur. Additionally, the system may stop responding.

This problem occurs approximately one time in every 500 restarts. Therefore, you usually experience this issue only when you are running restart tests. However, the risk of this problem occurring increases significantly if the following conditions are true:

• You apply hotfix 952681 on the computer.
• You insert PCI Express cards that do not fully support ASPM into all available PCI Express slots.

Consider the following scenario:

• You have a computer that is running Windows Vista or Windows Server 2008.
• The computer has the User Account Control (UAC) and Internet Explorer 7 protected mode enabled.

In this scenario, Internet Explorer 7 may stop responding when you try to visit any Web site. When this problem occurs, a blank Internet Explorer window appears, and the pointer circles constantly. To escape this condition, you must end the Internet Explorer process (Iexplore.exe) in Task Manager. Or, you must restart the computer.

Notes

• Typically, this problem occurs the first time that you start Internet Explorer after the computer starts or when the computer resumes from sleep or suspend mode.
• Sometimes, the Internet Explorer does not start when you double-click the Internet Explorer icon.

You have a Windows Vista-based computer that has an Secure Digital (SD) memory card inserted. You resume the computer from the system Hibernate mode (the S4 power state). Then, you try to shut down or restart the system. In this scenario, the system may stop responding on the shutdown screen.

When the issue occurs, you must remove the SD memory card to recover the system. Or, you must press the power button to forcibly shut down the computer.

Notes

• Removing the SD card may cause data loss.
• Sometimes, after you resume the computer from the system Hibernate mode, some applications may stop responding.
• This problem does not occur on a Windows Vista Service Pack 1 (SP1)-based computer.

Consider the following scenario:

• On a Windows Vista-based computer, you have the Tablet PC Input Service enabled and running.
• The Tablet PC Input Panel has started.
• You open an online service in Media Center. For example, you open an Internet TV program or an online movie in Windows Media Center.

In this scenario, Windows Media Center may stop responding. Sometimes, the online service can load its content. However, Windows Media Center responds slowly when you try to interact with it.

When this problem occurs, you have to restart the computer or wait for Windows Media Center to reload the main page.

Note: In this scenario, you cannot end the Windows Media Center process in Task Manager.

Consider the following scenario:

• You configure a computer to use the Windows Aero color scheme feature.
• You capture a screen shot by pressing PRINT SCREEN on the keyboard.
• You move or resize the target window while you capture the screen shot.

In this scenario, the screen freezes, and you have to restart the computer.

This problem occurs when the computer is running one of the following:

• Windows Vista that has hotfix 937229 installed
• Windows Vista SP1
• Windows Server 2008

Notes

• When you press PRINT SCREEN to capture a screen shot, the BitBlt function or the StretchBlt function is called.
• If you use an application that calls the BitBlt function or the StretchBlt function, this problem may also occur.

Symptom 1

Consider the following scenario:

• On a computer that is running the release version of Windows Vista, a volume on the hard disk is corrupted.
• You restart the computer.

In this scenario, a black screen is displayed, and you cannot log on to the computer except in safe mode.

Symptom 2

Consider the following scenario:

• On a computer that is running Windows Vista Service Pack 1 (SP1) or Windows Server 2008, a volume on the hard disk is corrupted.
• You restart the computer.

In this scenario, the Autochk.exe application stops responding, and this prevents the restart process from continuing. If you press a key to cancel the Autochk.exe process, you can log on to the computer as expected.

Note: By default, the Autochk.exe application automatically tries to fix any hard disk corruption during startup. After Autochk.exe fixes the disk corruption, the system automatically restarts.

Consider the following scenario. On a Windows Vista-based computer, you install a series of hotfixes without restarting the computer. Then, you try to restart the computer to complete the hotfix installation. However, the system may stop responding (hang) while the computer is shutting down. The shutdown process stops responding at the following message:

Windows is configuring the updates

This behavior continues until you manually turn off the computer.

Consider the following scenario:

• You are running a Windows Vista-based computer that has multiple USB devices connected to it. Or, you are running a Windows Vista-based computer that has a docking station that has multiple USB devices connected to it.
• You install a Bluetooth device on the computer. Then, you turn the device on.
• You try to put the computer into hibernation ((S4).

In this scenario, the computer stops responding.

When you start a Windows Vista-based computer, the system may stop responding (hang) at a black screen.

Additionally, you may experience the following symptoms when you try to recover from this problem:

• If you restart the computer, press F8 before the Windows Vista progress indicator appears, and then click the Safe Mode option, the same problem occurs.
• If you start Windows Recovery Environment (WinRE) to restore the Windows Vista-based computer, WinRE stops responding.
• If you try to use Windows Vista installation media to repair the system, the system stops responding.
